This is a WordPress site with nginx running in a Docker container on Raspberry PI3.<\/p>\n

\"\"<\/p>\n

This site is a demo about running a LEMP (Linux+Nginx+MySql+PHP) on a hardware low-power consumption.<\/p>\n

The Raspberry model B normally consumes 230 mA when in idle mode while using 500 mA at least with no device connected ( see https:\/\/raspi.tv\/2018\/how-much-power-does-raspberry-pi-3b-use-power-measurements<\/a> and  https:\/\/www.raspberrypi.org\/documentation\/hardware\/raspberrypi\/power\/README.md<\/a> ) , anyway the power of a Raspberry model B is less than 4W. <\/p>\n

It’s running Raspbian, based on Debian 8.<\/p>\n

Docker is v. 1.12.4 , nginx is 1.6.2 and kernel 4.4.34-v7.<\/p>\n

WordPress is 4.9.8 and using plugins like Metaslider, Google Doc Embedder and other.<\/p>\n

There is another container<\/a> running nginx with  a WikiMedia<\/a> site .<\/p>\n

 <\/p>\n

And now the system is growing … <\/p>\n

\"\"<\/p>\n

The stack is made up by 4 Raspberry running Kubernetes as 1 Master and 3 Nodes …  <\/p>\n

After some problems with SD cards, following the link  https:\/\/www.raspberrypi.org\/documentation\/hardware\/raspberrypi\/bootmodes\/msd.md<\/a>,  the cluster Kubernetes is booting from USB key with a significative performance improvement.<\/p>\n

If you’ve a B3+, everything is OK but, if you’re using a B3, you have to add the parameter program_usb_boot_mode=1<\/strong> to the file \/boot\/config.txt <\/p>\n","protected":false},"excerpt":{"rendered":"
